What happens if your AC pressure switch is not working?
If it is not functioning, then the system can not operate, and will be unable to produce cold air. Because the AC pressure switches play such a vital role in ensuring the proper operation and service life of the AC system, any problems with them should be addressed immediately to ensure the integrity of the system.
Why is my air conditioning not working in my PT Cruiser?
When waiting for a traffic light the A/C vents start blowing warm and the compressor cycles very fast. (driving along is fine, ice cold air) I noticed the electric fan was not working. At home in the driveway it works perfect. It idles with the fan running and ice cold air out of the vents all day. Anyone else have this problem?
Why is my air conditioner pressure so high?
Not sure what is causing the pressure to rise so high, but it appears that there may be a blockage in the system restricting the refrigerant flow. When your high side pressure spikes to 400psi or higher, that could mean that you might have a bad radiator fan motor,or a bad fan relay.
Why is my AC compressor not coming on?
Compressor not coming on As the pressure switches control the on/off function of the AC compressor, a switch failure can prevent the AC compressor from functioning at all. The compressor is what pumps refrigerant through the entire system. If it is not functioning, then the system can not operate, and will be unable to produce cold air.
Why is my a / C not blowing cold air?
Check for cold air being blown into the cabin. If the A/C does not blow cold, this could indicate a faulty compressor or a lack of refrigerant in the cooling lines. Remove the blue cap on the low-pressure line.
What does it mean when your a / C system is not working?
If you have pressure that falls within the green band on the pressure gauge, then the A/C system is pressurized—meaning there is refrigerant in the lines. If you are not blowing cold air in the cabin, it means that the compressor has failed. If there is no pressure or low pressure in the lines, there is a leak somewhere in the lines.
Why is my a / C not working on my PT Cruiser?
If you are not blowing cold air in the cabin, it means that the compressor has failed. If there is no pressure or low pressure in the lines, there is a leak somewhere in the lines. Many times when the compressor fails, there is also a leak at the compressor.
What to do if your a / C unit fails?
If there is no pressure or low pressure in the lines, there is a leak somewhere in the lines. Many times when the compressor fails, there is also a leak at the compressor. So have the lines checked by a professional mechanic; if he finds no leaks, then replace the compressor.

Is there a high and low pressure switch?
There are both high pressure and low pressure switches; some vehicles are equipped with just a high pressure switch while others have both. Incorrect pressure can damage the compressor, hoses, and other A/C system components.
Do you need to unscrew a pressure switch?
Loose the switch with a socket or wrench, then unscrew it. Note: Typically, the A/C system does not need to be evacuated prior to removing the A/C pressure switch. This is because there is a schrader valve built into the switch mount.
What are the signs of a bad air conditioner switch?
Common signs of failure include a bad compressor or lack of AC. Air conditioning pressure switches are designed to protect the A/C system against pressure that is too high or too low. There are both high pressure and low pressure switches; some vehicles are equipped with just a high pressure switch while others have both.
